[Class 8(i)] A compressor comprises a crankcase rotatably supporting a single throw horizontal crankshaft and having mounted thereon at least one low pressure cylinder at a substantial angle to the horizontal and at least one high pressure cylinder at a substantial angle to the low pressure cylinder and an inter-cooler supported by the cylinders and lying wholly above the lowermost point in the low pressure cylinder so that a driving device can be located in line with the crankshaft above the bottom of the crankcase and below the inter-cooler. In one example the compressor comprises a crankcase 1, a single throw crankshaft 51, low pressure cylinders 2, 3, having double acting pistons 45, inlet valves 19, 20 and outlet valves 28, 29, high pressure cylinders 4, 5, having double acting pistons 46, inlet valves 39, 40 and outlet valves 41, 42; and intercoolers 32, 33 supported by the cylinders and connecting the cylinders 2, 4 and 3, 5. The crankshaft 51 is driven by an electric motor 57. Compression is controlled by pilot valves 69, 70, 71, 72 (see Fig. 8), which are connected to the compressor discharge by a pipe 69a. At a predetermined pressure the pilot valve 69 supplies air to open the inlet valves 20, 40 of cylinders 2, 4, at a higher pressure valve 71 operates to supply air to close a valve 11 in the inlet to the cylinder 2. Subsequent higher pressures operate valves 70, 72, to open the inlet valves 20, 40 of the cylinders 3, 5 and close the valve 11 in the inlet to cylinder 3, respectively. A vent control device (not shown) is provided on each high pressure cylinder to vent the not-directly-unloaded ends to atmosphere when the valves 11 are closed. The intercoolers are water cooled and lubricating oil in the crankcase 1 is cooled by cooling pipes 64 through which water flows. The Specification also describes a two cylinder compressor with a single inter-cooler and also a two cylinder compressor having a radiator type inter-cooler cooled by two fans driven from the crankshaft.

Title: Production of ester derivatives of dextran
IPC: C08B37/02
Filed: 1938-07-26
Abstract: 517,398. Dextran esters. STAHLY, G. L., and CARLSON, W. W. July 26, 1938, No. 22236. Convention date, July 29, 1937. [Class 2 (iii)] In a process of producing ester derivatives of dextran, a culture medium containing sucrose is inoculated with bacteria of the genus Leuconostoc, particularly L. mesenteroides or L. dextranicum, dextran is synthesized by the action of the bacteria on the medium, and is submitted to esterification, either with or without previous separation from the culture medium. The dextran may be first submitted to etherifaction with an alkyl or aralkyl halide before esterification. Plastic products are obtained which are suitable for making coating compositions, such as paints, varnishes, lacquers and enamels. Nitrogen containing material, e.g., in the form of peptone or beef extract, may be added to the sucrose source, but if the latter is molasses, such addition is unnecessary. Salts such as dipotassium phosphate and sodium chloride may also be added, and the medium is preferably maintained slightly alkaline during the fermentation. The dextran may be isolated by precipitation with alcohol or acetone. In examples, fermented culture media containing the dextran are converted into benzyl, butyl or #-hydroxyethyl ethers by treatment with benzyl or butyl chlorides or ethylene chlorbydrin, and the products are esterified by treatment with an organic acid chloride or anhydride.

Title: Improvements relating to motor fuels
IPC: C10L1/02
Filed: 1937-08-13
Abstract: A motor fuel comprises a blend of hydrocarbons boiling within the gasoline range and a normally liquid ether boiling within said range and of the formula R-O-R1, where R and R1 are hydrocarbon groups at least one of which is a branched aliphatic radicle, in which is incorporated between about 0,001-2,0 per cent of a low molecular weight organic liquid which is sufficiently soluble in water to lower the freezing-point to such an extent as to prevent solidification of any aqueous liquid that may separate from the fuel when cooled to low operating temperatures.  Suitable anti-freeze liquids are methanol, ethanol, propanol, isopropanol and tertiary butanol; ketones such as methyl ethyl ketone; or polyhydroxy compounds such as ethylene glycol; less suitable are dimethyl ether, ethyl ether, formaldehyde and acetaldehyde.  Generally, the addition is from 0,01-1,0, and, preferably, 0,1-0,5 per cent.  The fuel may contain other addition agents, e.g. anti-knock agents such as lead tetraethyl, gum inhibitors such as tricresol, alpha-naphthol or benzyl paramidophenol, and light stabilizers or dyes.  Suitable branched ethers are those of the type disclosed in Specification 445,503, e.g. isopropyl-, tertiary butyl-, methyl tertiary butyl-, methyl tertiary amyl-, ethyl tertiary butyl-, isopropyl tertiary butyl-, and di-tertiary butyl ethers.  An example is given of a fuel containing isopropyl ether with an addition of methanol.  The Specification as open to inspection under Sect. 91 describes also the addition of such anti-freeze liquids to fuels containing blending agents other than branched ethers, e.g. phenyl methyl ether, tertiary amyl alcohol, di-isopropyl ketones, aniline and toluidine.  This subject-matter does not appear in the Specification as accepted.
